TANK.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed April 22,19074 Serial No. 369,609.

walls thereof with a terminal circumferential tube or bead which notonly increases the rigidity of said walls but also forms a smoothbearing surface for the upper orfree edge of the tank.

A still further object of the invention is to generally improve thisclass of devices so as to. increase their utility, durability andelliciency.

Further objects and advantages willappear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accomjuinying drawings forming a part of this specification: l41igure l is a vertical sectional .view ofy a. tank constructed inaccordance with my invention. Fig. l is a side elevation partly insection of a portion of the upper part of the tank.

Similar numerals of reference indicate corresponding parts in all of theiigurcs of the drawings.

The improved tank forming the subject matter of the resent invention ispreferably cylindricalin sliap'c and formed of sheet metal or othersuitable material, said tank having an in'ipen'foratc bottoni 5 andverticallyT disposed sidewalls (i connected with the bott-oni 5 by a lapjoint 7.

Secured Ato the upper or free edge of the vertical walls 6 is acircumferential rcinforc ing tube or bead 8 having a recess 9 formed inthe bottom thereof andY adapted to receivethe adj acont edge of the tankthereby to reinforce and strengthen the walls of the tank and. also formajsmooth bearing surface at the upper edge of the latter.

Disposed within the tu be S at the meeting ends l() is a sleeve orcollar 11 also provided with a slot 12 for vthe rece )tion of the upperedge of the tank, said sleeve or coupling member being so arranged as tooverlap the ends l0 of the tube 8 andA thus form a rigid como ectionbetween the saine.

Embracing the exteriorwalls of the tube 8 at the meeting ends 10 thereofis aclamping member 12 prefcrabl formed of a single piece of metal thelower longitudinal edges of which are bent inwardly to forrnattachinglianges 13 which bear against the interior and exterior faces of theadjacent vertical walls 6 and are secured thereto in any suitable manneras l'by bolts, rivets or similar fastening devices 14.

The clamping member 12 is further secured in position on the split tube8 by means of transverse bolts or rivets 15 whichl extend through theclamping m'ember 12/ and coupling member 11 and also ierce the adjacentportion of the vertical wa l 6, there being similar bolts or fasteningdevices. 16 disposed at spaced intervals around the split tube andextending transversely through the same and through the walls of thetank thereby to securely fasten the split tube in position on the top ofthe tank.

Soldered, riveted or otherwise rigidly secured to the lower portion ofthe tank is a reinforcing band or hoop 17 rovided with-a lateral offsetportion 1S whic i forms a casing or housing for the connection between`-the bottom and side walls of the tank so as to prevent injury to thelatter. One edge of the band or hoop bent in engagement with the sidewalls of the tank to produce an.

inclined shoulder 16 while the opposite edge thereof is extendedlaterally beneath the bottom of the tank to form a reinforcing ring 19which also serves to receive and sustain the weight of the tank andprevent undue wear on the bottom thereof.

Having thus described the invention what is claimed is:

1. A tank having its upper edge reinforced by a split tube, 'a cou )lingmember engaging the interior walls of tile tube at the abutting endsthereof, and a clamping member embracing the exterior walls of 'the tubeand l having its opposite longitudinal edges spaced apart and secured tothe interior and exterior walls of the tank.

.2. A tank having its upper edge reinforced by a split tube, a cou )lingmember engaging the interior walls of the tube at the abutting endsthereof, a clamping member embracing the exterior of the tube and havingits adjacent ends bent laterally to forni attachin fianges forengagement With the interior an exteriorvwalls of the tank, resectively, and

'fastening devices piercing said flanges..

3. A tank having its upper ed e reinforced .by a split tube, a tubularcou ing member engaging the interior walls of t le tube at the abuttinends thereof and provided with a. iongitu inal slot for the reception ofthe `Vertical Wellof the tank, a clamping member clamping andcouplinvmembers and piercing 10 the vertlcal well of t e tank.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two Witnesses.
